Radar has mapped what appears to be a gladiatorial school from the ancient Roman Empire. The ruins, which are underground, were located east of Vienna. They've created a model of the ruins and it's definitely going to be interesting to see what they unveil over time as they dig, restore, dig, restore, and so on and so forth. Please share your thoughts (as I'm not a Romanist by any means).
